Objective To observe the curative effect of nicergoline in the treatment of chronic cerebral circulation insufficiency ( CC-CI) . Methods 160 cases with CCCI were randomly divided into the treatment group which were administered 10 mg of oral Nicergoline, three times per day for one month,and the control group which were given 20 mg of oral nimodipine,three times per day for one month. The clinical effective rate and the transcranial Doppler ultrasound ( TCD) between the two groups before and after treatment were observed. Results There were significant difference in clinical effective rate and TCD index assessment between the two groups(P<0. 05). Conclu-sion Nicergoline is an effective and safe treatment for chronic cerebral circulation insufficiency.

Objective To study the changes of Toll like receptor 4,7 (TLR4,TLR7) protein in cervical squamous cell carcinoma ( CSCC) tissues and the relationship between expression and clinical pathological characteristics of the patients. Methods A total of 67 pa-tients with CSCC carcinoma( CSCC group) ,30 patients with cervical intraepithelial neoplasia( CIN group) and 30 patients with normal cervi-cal tissues(normal group) were detected by immunohistochemical method. The expression of TLR4,TLR7 protein and its clinical pathological characteristics of patients with CSCC in the samples were analyzed. Results TLR4,TLR7 protein positive rate of CSCC group were respec-tively 80. 60% and 76. 12%,which were significantly higher than those of CIN group (46. 67%,40. 00%) and the normal group(13. 33%, 10. 00%),the difference was statistically significant (P<0. 05). TLR4,TLR7 protein positive expression rate in CIN group was significantly higher than that in the normal group (P<0. 05). The positive expression of TLR4 protein and CSCC in patients with FIGO stage,pathological grade,depth of invasion had a significant relationship(P<0. 05),pathological grade,the positive expression of TLR7 protein and CSCC in pa-tients with invasive depth had a significant relationship(P<0. 05). Conclusion There is increased expression of TLR4,TLR7 protein in cervical tissues of CSCC patients,and a certain relationship between the factors and clinical staging,pathological grading.

This study investigated the effect of arctigenin (Arc) on the cell activation, cytokines expression, proliferation, and cell-cycle distribution of mouse T lymphocytes. Mouse lymphocytes were prepared from lymph node and treated with Phorbol-12-myristate-13-acetate (PMA)/Ionimycin (Ion) and/or Arc. CD69, CD25, cytokines, proliferation and cell cycle were assayed by flow cytometry. The results showed that, at concentrations of less than 1.00 micromol x L(-1), Arc expressed non-obvious cell damage to cultured lymphocytes, however, it could significantly down-regulate the expression of CD69 and CD25, as well as TNF-alpha, IFN-gamma, IL-2, IL-4, IL-6 and IL-10 on PMA/Ion stimulated lymphocytes. At the same time, Arc could also inhibit the proliferation of PMA/Ion-activated lymphocytes and exhibited lymphocyte G 0/G1 phase cycle arrest. These results suggest that Arc possesses significant anti-inflammatory effects that may be mediated through the regulation of cell activation, cytokines expression and cell proliferation.

ObjectiveTo study the effect of behavior training on the expression of NR2B around the infarcted focus and in the cortex of temporal lobe in rats with bilateral hippocampal infarction.Methods54 SD rats were randomized into pre-training, 7 d, 14 d, 21 d after training groups, pre-immobilization, 7 d, 14 d, 21 d immobilization groups and control group. Behavior training and immobilization were performed on the 3rd day after the infarction. Immunohistochemistry was used to detect the expression of NR2B around the infarcted focus and in the cortex of temporal lobe at different points of time.ResultsThe expression of NR2B was abundant in the normal hippocampus and cortex of temporal lobe of rats. The expression of NR2B decreased after infarction and increased after behavior training. However, the expression of NR2B had little increased in immobilization groups, and showed significant difference compared with that in behavior training groups (P<0.01).ConclusionBehavior training can accelerate the expression of NR2B around the infarcted focus and in the cortex of temporal lobe in rats with bilateral hippocampal infarction.
